TACK-LIFTER.

SPECIFICATION forming part of Letters Patent No. 491,818, dated February14, 1893. Application filed January 21, 1892. Serial No. 418,751. (Nomodel.)

.To all whom it may concern:

Be it known that 1, MARK ALDRICH SHED DON, acit-izen of the UnitedStates, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inTack-Lifters, of which the following is a specification, reference beinghad therein to the accompanying drawlngs.

This invention relates to new and useful improvements in tack lifters,and the invention consists in the peculiar construction and arrangementsof parts hereinafter described and definitely pointed out in the claims.

In the, drawings, Figure l is a perspective view of my improved lifter,showing the tack lifted and in the claw. Fig. 2 is a front elevationthereof. Fig. 3 is an enlarged side elevation partly in section. Fig. 4is a vertical central, longitudinal section showing the manner ofclamping the tack in the claw.

A is the shank. B is the handle of a tack lifter. The shank A isstraight, having flat top, and bottom sides and is provided at one sidenear the forward end with an arm 0 forming the fulcrum upon which toturn the lifter, after the claw is engaged with the tack to pulljt. Thisconstruction forms the subject matter of Letters Patent granted to medated December 29, 1891, No. 466,066. The claw portion, as shown in Fig.3, is formed with a curved or beveled under face constituting a wedge orshort lever for'engaging beneath the tack. In the upper face I form arecess a which extends from the sharp edge at the point of the claw inan inclined plane up to the shank, as plainly shown in Fig. 3, thevertical side flanges I) being formed at either side, as plainly shownin the drawings.

To hold the tack in the lifter after it has been withdrawn I provide aspring clamp D, preferably a flat spring, secured upon top of the shankand extending to near the front of the claw. This spring I provide atits forward end with a depending foot E, which engages into the recessabetween the flanges b, and also with an upturned lip F to allow thehead of the tack to be engaged between it and the claw, as plainly shownin Fig. 4. When the tack has been lifted the spring clamp holds ittightly in position, as shown in Fig. 4 by clamping the head between thefoot E and the claw, and it maybe then s dropped into the receptacle Gby simply drawing across the edge thereof, as shown in Fig. 4.

What I claim as my invention is:

1. A tack lifter consisting of a shank having a claw at its end formedwith a centrally recessed upper face and a spring secured to the shankextending forward and bent down or curved at its end forming a footnormally resting in said recess, and having an upturned lip at its endsubstantially as described.

2. In a tack lifter the combination with the handle, of aclaw having abeveled under portion, a recess at the end of the claw havinga bottomformed in an inclined plane and vertical side flanges, a spring securedon the shank extending down over the claw having an upturned lip at itsend and a depending foot entering the recess and adapted to clamp thehead of the tack therein, substantially as described.

In testimony whereof I my signature in presence of two witnesses.

MARK ALDRICH SHELDON.
